I kind of like you analogy. Let me add to it. Dad has tunnel vision on the Nic, the kids are all screaming in the back that they want this, they want that, they deserve.... all while hitting Dad on the back of the head. Mom has a migraine from trying to settle everyone down. And, we are about to miss the exit.
Why don't we all settle down, stop fighting the past battles and keep our eyes on the road? Naw, it will never happen and in a few years we will try to remember what caused the wreck when we wake up in the hospital. Then we can start "IT WAS YOUR FAULT! NO, IT WAS YOURS!".
